I am trying to put additional functionality in this code to delete rows with "3/25/2005" or "12/31/2004" in column A.

This doesn't work, yet it doesn't give any errors.
When i check my sheet, it deletes duplicate rows but not the rows with "3/25/2005" or "12/31/2004".
Please can anyone take a look? Thanks 

'DELETE DUPLICATE ROWS AND DELETE ROWS WITH CRITERIA
Dim i As Long 
Dim cursheet As Worksheet 
Set cursheet = Worksheets("DataTable") 
For i = cursheet.Cells(Rows.Count, "A").End(xlUp).Row To 2 Step -1 
    If WorksheetFunction.CountIf(cursheet.Range(cursheet.Cells(2, 1), cursheet.Cells(i, 1)), cursheet.Cells(i, 1)) > 1 Or _ 
    Cells(i, "A").Value = "3/25/2005" Or _ 
    Cells(i, "A").Value = "12/31/2004" Then 
    cursheet.Cells(i, 1).EntireRow.Delete 
End If 
Next i
